NGC 6362 is a globular cluster in the constellation Ara, lying close to Apus in the southern sky. Tightly bound by gravity, globular clusters are composed of old stars, which, are around 10 billion years old, and much older than the sun. These clusters are fairly common. there are more than 150 currently known in our galaxy, the Milky Way, and more which have been spotted in other galaxies. All stars are usually around the same age in a given cluster. Most of the stars inside the cluster are thought to have formed at or around the same time and are thought to be of similar age. Most of the stars inside NGC 6362 are red giants that appear yellow and aged, however, you also see a number of so-called blue stragglers, stars that appear younger than their true age. Blue stars are hot and consume their fuel quickly.

So nice to see a globular cluster in plausible colours. Even the professional popular sites are not above making them blue-white so they look pretty, but they cannot possibly be ten billion years old and blue, or even blue-white. They can't even be ten million years old and blue. As you say, they will have a smattering of blue stars due to the collision and merger of close binaries, and they will be bright and salient, but they are in the extreme minority. You have it right.
